Potion of Giant Control
A full potion of this draft must be consumed for its effects to be felt. It will influence one or two giants like a Charm Monster spell. Control lasts for 5d6 rounds. If only one giant is influenced, it is entitled to a saving throw vs. spell with a -4 penalty; if two are influenced, the die rolls gain a +2 bonus - effectively weakening the effect of the potion. The type of giant subject to a particular potion is randomly determined.
